Cingal is a prescription treatment that provides relief from pain that is associated with osteoarthritis in the knee. Cingal consists of two medications that both act to provide this pain relief. On one hand, Cingal has hyaluronan that helps to lubricate and cushion the joint for the prevention of further joint damage, and on the other hand, it contains a steroid that acts rapidly to reduce inflammation and pain in the knee. The pain-relieving effects of Cingal can last up to 26 weeks with just a single dose.
